3种方法治疗翼状胬肉的临床观察

目的比较翼状胬肉的常规切除术、羊膜移植术（Amniotic membrane transplantation，AMT）及AMT联合自体角膜缘移植术（Limbal autograft transplantation，LAT）对翼状胬肉的治疗效果：方法95例（97只眼），翼状胬患者随机分成3组，分别采用常规胬肉切除术、AMT及AMT联合LAT进行治疗．比较复发率。结果常规胬肉切除组复发半66．67％．AMT组复发率18．18％．AMT联合LAT组复发率0％。3组两两比较，差异有显著性：结论AMT联合LAT治疗翼状胬肉效果良好。

Comparative study of cure effects of amniotic membrane transplantation combined wity limbal autografts transplantation for the pterygium

Objective To study effects of conventional pteryium excision , amniotic membrane transplantation with or without limbal autografts for the treatment of pterygium. Methods 95 patients were qrouped and treated with conventional pterygium, amniotic membrane transplantation (AMT)and AMT with limbal autograft transplantation (LAT).
